WinZip, developed and released by Corel Corporation in 1991, is a compressor and file archiver. With WinZip, users can pack any form of document that they'd like into collective .ZIP archive files. Users may unpack not only .ZIP files, but also .BZ2, .RAR, .LZH, .7Z, and .BZ2 files as well.

Winzip's archive encrypting capabilities are compatible with the majority of all social networks and applications made for cloud storage. Users have reported that compared to the default archiver included in Windows, WinZip is slightly faster. The optional ZipSend service can be used to create sizable email attachments out of archives and deliver them instantly.
